The last meeting was held in 2953 to discuss the OneRing, but Saruman lied about the fate of the Ring in order to quieten Gandalf's suspicions about Bilbo's ring and hence gain more time to get hold of it.

Notes

According to the "History of Galadriel and Celeborn" in UnfinishedTales?, a Council--described as "the first Council"--was held c. SeA 1700, after the defeat of Sauron's forces in Eriador, at which it was decided "that an Elvish stronghold in the east of Eriador should be maintained at Imladris rather than in Eregion." At this Council Gil-galad made Elrond his vice-regent, and gave him Vilya, the Blue Ring.

The members of this Council probably included many of those who would belong to the Councils of the Third Age, excepting of course the Wizards.
